PECIPICATION forming part of Letters Patent No. 302,251, dated July 22, 1884.

Toall whom it may concern:

Be it known that we, Orro HELLER, of West Oovington, Kentucky, and WILLIAM DONALD- soN, of LudloW, Kentucky, have invented new and useful Improvements in Independent Reservoir-Lamps, of which the following is a specification.

Our invention relates to that form of lamp in which the bottom of the reservoir and the wick-tube are connected by the oil-tube, while a brace extends above said oil-tube from the reservoir to the Wick-tube.

Our improvement consists in a peculiar form of brace which does duty as a support for the shade-ring as well as for the reservoir and wick-tube; and, further, is connected to the sleeve whose collar has an opening through it on one side to connect the reservoir and wicktube portions of the oil-tube, and is formed solid on the other side to give a substantial bearing to the set-screw which secures the lamp at the required height on the standard all as hereinafter described, and pointed out in the claims.

In the drawings, Figure 1 is aside view of a lamp having our improved construction, the ends of the oil=tube and adjacent parts being sectioned. Fig. 2 is a horizontal section of the collar and adjacent parts.

Ais our improved brace, fitting around the standard F, secured to the top of the sleeve D in place otthe ordinary oil-tube globe or ball, and having an arm, a. to support the reservoir B, a vertical arm, a, to support the shade-ring, and an arm, a, provided with a collar, H, surrounding the wick-tube O, and forming a support theretmas well as to the outer end of theoil-tube, which is connected through it with the wick-chamber.

G is a horizontal oil-tube extending from the bottom of the reservoir to the wick-tube. The collar E at the lower end of the sleeve has an opening, 6, through it on one side to connect the reservoir and wick-tube portions (No model.)

of the oil-tube conduit. The other side, e, of 4 5 following is what we claim as new therein and desire to secure by Letters Patent 1. In an independent reservoir-lamp, a brace connecting the reservoir, wick-tube, shadering, and standard, as set forth.

2. In an independent reservoir-lamp, the combination of a reservoir, a wick-tube, and a horizontal oil-tube having a collar, and a setscrew working in one side of the collar, the

oil-tube connecting the reservoir to the wicktube through the other side of the collar, as set forth.

3. In an independent reservoir lamp, a brace, A, having arm a to support the reservoir, an arm, a, to support the shade-ring, and an arm, a, provided with a collar, H, to support the wick-tube and outer end of the oiltube, as set forth.

4. In an independent reservoir-lamp, the combination of a brace connecting the reservoir to the wick-tube, and the horizontal oiltube connectingthebotto-m of thereservoirwith the wick-tube, having a collar whose sleeve extends upwardly, the collar being formed with an oil-passage on one side and provided with a set-screw on the other, as set forth;

The foregoing specification of our invention signed by us this th day of October, A. D. 1883.
